Zillionth

Zillionth is a funny or exaggerated way to say something has happened too many times to count. It’s not a real number like “million” or “billion”; it just means “a very large number”. For example, they told that story for the zillionth time! You use “zillionth” when you’re tired of hearing or doing something again and again. It shows annoyance or exaggeration, not an exact count.
